NELSON, OF CHICAGO HEIGHTS, ILLINOIS, ASSIGNOR T ZOURI DRAWN METALS COMPANY, OF CHICAGO HEIGHTS, ILLINOIS, A CORPORATION OF ILLINOIS SASH CONSTRUCTION Original No. 1,687,305, dated October 9, 1928, Serial No. 212,936, filed August 15, 1927. Application for reissue filed April 21, 1930.

This invention relates to sash construction especially adapted for use in store fronts and the like for setting plate glass.

The object of the invention is to provide a simple and improved device, which may be easily secured in position to clamp the glass, and which may be easily adjusted to exert the desired pressure on the glass without injury thereto.

The novel features of the invention and the advantages thereof will be more fully explained 1n"the following detailed description taken in connection with the accompanying drawing which illustrates various forms thereof.

In the drawings: Fig. 1 is a perspective view illustrating one embodiment of the invention;

Fig. 2 is a view similar to Fig. 1, but showing a modified form of molding;

Fig. 3 is a perspective view of the draw plate as used in Figs. 1 and 2;

Fig. 4 is a perspective view of another embodiment of the invention; and

Fig. 5 is a perspective view of the draw plate shown in Fig. 4.

In the form illustrated in Fig. 1 there is provided a channel-shaped clamping member 1 having a side wall 2 terminating in a face 3 80 against which the glass 4 rests. The other side wall 5 of the channel member is formed with ribs 6 and 7, adapted to rest against the window frame or other support, leaving a space 8 between the side wall and its support for receiving the backwardly turned flange 9 of the face moulding 10. The upper edge of this moulding is formed with an inturned flange 11 having a face adapted to bear against the front surface of the glass 4. In order to provide means for bringing the members 1 and 10 into clamping relation to the glass the member 10 is provided on its inner face with a channel 12 having inturned side flanges 13 overhanging its edges. Cooperating with the channel 12 and flanges 13 are a number of draw plates 14, one of which is shown in Fig. 1. This draw plate is formed with a knee 15 adapted to bear against the side 5 of the inner clamping member and slopes away from the side 5, as indicated at 16,

Serial No. 446,1 12.

and has a laterally turned end portion 17 which extends between the flanges 13 and terminates in a head 18 within the channel 12. The head 18 is formed with shoulders 19 adapted to engage the inner edges of the flanges 13. The other end of the draw plate also slopes away from the side wall 5, as indicated at 20, and terminates in a backwardly turned flange 21 which engages the inner face of the wall 5. A key actuated screw 22 extends through the wall 2 and has a rounded end adapted to engage the inclined surface 20 to draw the clamping member 10 inwardly as the screw 22 is advanced. As the member 10 is thus drawn into clamping relation to the glass, the engagement of the flange 9 underneath the wall or flange 5 positively prevents movement of either the member 10 or the draw plate 14 relative to the glass, except in a direction substantially perpendicular to the plane of the glass. The sloping end portion 20 of the draw plate may be of sufficlent extent to allow for glass of any thickness.

Theinvention as shown in Fig. 2 is similar to that shown in Fig. 1, except that the face moulding 10 is of different style. It is obvious that the same principles of construction and operation may be used in connection with moulding of any style or design desired.

In the form of the invention shown in Figs. 4 and 5, the inner clamping member 1 is substantially the same as in Figs. 1 and 2. The outer clamping member 23 has a lower flange 24 adapted to be received in the space 8 beneath the wall 5 and has at its opposite edge a flange 25 adapted to bear against the glass 4. The channel 26 formed in the inner face of the member 23 has similarly curved side walls and has an overhanging curved flange 27 which terminates in a rounded edge 28, which is substantially at the center of curvature of the side walls of the channel. The draw plate 29 is formed with a knee 30 adapted to bear against the wall 5 of the inner clamping member 1 and has an upwardly sloping portion 31 terminating in a curved end 32 which may be inserted laterally in the channel 26 and pivots about the rounded end 28 of the flange 27. The other end of the draw plate 29 has an upwardly sloping surface 33 and terminates in a backwardly turned flange 34. The screw 22, therefore, is adapted to engage the surface 33 and to draw the moulding 23 into clamp ing relation to the glass in substantially the same manner as the moulding 10 or 10 is drawn inwardly by means of the draw plate 14. v

The draw platesla are connected with the front face moulding by inserting the heads'18 into the end of the channel 12 and sliding them longitudinally therein to the point de sired. The draw plates 29 effect the same function as the draw plates 14:, but may be in serted laterally in the channel 26 and form substantially a hinged connection with the face moulding. r I I i I From the foregoing description it will be seen that I have provided a construction in which the glass may be set with the greatest facility and which is particularly adapted for use in extruded key-set sash construction. While I have shown and illustrated various forms inwhich the invention may be embodied, it is, of course, apparent that other modifications may be devised which will accomplish substantially the same results without any material departure from the scope of the invention as claimed.
